Ihad a very noisey cat that has now failed. No exhaust pressure out one side of exhaust. There is no way I'm pay $1600 for a oem replacement. I've been looking around for o2 simulators for this car (00 4.2) and cant find any. I want to cut out my cats and resonater. Have any of you guys used simulators with good success? Where did you get them from?

 

Somebody must have did or looked into this?

 

try http://convertergeek.com -- call them and ask about diff kinds they have. If you've used BG 44K to no avail, you have few options. Their pricing is from $350 - 600 per cat for the 2000 A6 4.2. Much cheaper than OEM.

Good luck!

I know exactly how you feel. Call Meineke. I have not yet, but found out on this forum some people who have successfully had cats installed (2) for $500-600. Not stock cats, but brand new and damn cheap comparitively.

Good luck!

 

simulators will not work. The motronic system will pick up on them and give you a cel just the same. Get some non fowlers for the car 420002 is the part # they have been working just fine for me
